Ahead of the high profile visits, U.S. State Department spokeswoman Jen Psaki said that Washington is open to Iran having a peaceful nuclear program but doesn’t recognize that any country has a right to enrich uranium.

Hence negotiations are on to reconcile these two positions. he move comes close on the heels of reports that EU foreign policy chief Catherine Ashton and Iranian Foreign Minister Mohammad Javad Zarif made significant progress on core issues.

The two sides have maintained that differences persist over Iran’s insistence on its right to enrich uranium, shutdown of its Arak heavy water reactor and the extent of the relief from sanctions.

Negotiations are on to reconcile the differences.
